Hi all, We are trying to install rancher 2.7 on k3s cluster(v1.23.17+k3s1) in a single node ec2 instance(t3.medium) We selected external tls and one replica. After the installation is done we are getting 404 page not found if we try to access rancher. I see some errors in the rancher logs

I'm a new to rancher and tried almost every solution that i found on google..

you are most likely running out of memory and rancher cant complete startup, its a pretty memory hungry app

starting up rancher inside of k3s

what does kubectl describe pod rancher -n cattle-system show?

the previous pod logs you'd be looking for error 137 if it is a memory issue
